Video: Atlas 5 GPS 2F-8 Launch Highlights

With its new homeport in renovated NASA space shuttle hangars off in the distance, the Air Force’s X-37 mini spaceplane will be launched from Cape Canaveral on May 6 for its fourth journey into orbit.

A layer of fog intruding on Vandenberg Air Force Base in California kept nearby observers from seeing any sign of Saturday’s predawn launch of an Atlas 5 rocket carrying a robotic NASA probe to Mars. The only images of the Atlas 5’s fiery takeoff came from remote cameras placed at the launch pad, or from distant viewing points away from the poor visibility.

The most powerful variants of the Atlas 5 and Delta 4 rockets have been purchased by the Air Force to launch intelligence-gathering spacecraft for the U.S. government, and NASA has bought an Atlas 5 to deploy a critical polar-orbiting weather satellite.
